Woo it is sweltering, which means we got to stay in and do a bunch of engineering. This week we spent a little time finishing up some languishing boards - Stemma QT version of the SCD40/SCD41 and IS31FL3741 chips - we wrote libraries for both as well! We also are dealing with a massive SAMD51 shortage by redesigning some recent boards like the Matrix Portal to be S2 only (so at least there's only one chip to source!)
The Great Search - BSS138 Dual N-Channel FET Alternative Replacement
www.digikey.com/short/5hh9bz4w
We use hundreds of thousands of the famed dual BSS138 n-channel FET in every one of our breakouts - we use them for I2C level shifting on our breakouts and QT boards. But, this ultra-jellybean part is suddenly...out of stock everywhere! No worries, lets show how to find a drop-in replacement so we aren't held up on manufacture.
"Hot girl summer is a meme, originating with rapper Megan Thee Stallion, about feeling confident in who you are-and having fun and looking good while doing it. It often involves women posting selfies with summery swag and style using the caption (I heard it's) hot girl summer." - megantheestallion.com/
